LoCoMoTivE STRUCTURE.

Application `filed June 21, 192.4. Serial o. 721,409.

coli/pt may cmcci'n: i kjnown :that I, HAI-nii' M. PFLAGER, a citizen of the United States, residingl at St. LouisLlllissoui'i. have. invented a certain new andusefiil Iiiipijoveinent in Locomotive Structures of which the following is a Specification', such asI will enable ,others skilled Ain the vart to which it appertains to make andusethewsame. p l

r inverntionrelates to railroad rolling stclaiid consists in an improved mounting of k(the.i locfoinotive`air pump and in a pilot beam adapted for such mounting.

The main `ob `ect of` my invention is to move theyair' pump cylinders as far forward of the locloniotiv'e as possible', thereby rei lievingthe y'driv'eis the weight of the air pump Iand utilizing space which is not required foroth 'l purposes.v

The 'same general Object is'attained in the structure illustrated andclaimed in my copending application y'SQerial Number 721,408, filed of even date herewith. y

(Y Amparticular object of my invention is to; Aseat the pump cylinders witlnn the pilot beam so as to reduce the space occupied by theassembly and to better protect the puni, elements: y

furtilier objfCll of present invention is t`o ycarry the vair reservoir bythe pilot beam in the preferred form of my invention I adapt theifpilotbeam toenclosje the air. reservoir and indeed to form the wervels. A, i1, tlie accompanying ydrawings which illustrate a selected embodiment of my inventioi1 Figure l is a top View of my improved pilot beam with the air pumps mounted thereon and with the pilot and the adjacent portion of the loco-motive frame indicated in dot and dash lines.

Figure 2 is a vertical section on line 2-2 of Figure 1.

Figure 3 is a front elevation of the parts shown in Figure 2.

The pilot beam 1 is shown as consisting of a one-piece casting, box-shaped in cross section, and adapted to be attached to the front end of the locomotive frame and to have a pilot secured to its forward face.

The top Wall of the beam is provided with openings near its ends and the rear Wall of the pilot beam is bulged outwardly at 2 adjacent the openings all for the purpose of receiving air pump cylinders 3 in lthe recess so formed. A vertical bracket l extends upwardly from the top of the beam in front of the opening therein and is provided with downwardly and rearwardly inclined reinforcing flanges5y located at the sides Vof the openingand forming withthe recessed body of the beam a housing substantially enclosing-the air pumpsteam and air cylinders.

The rear of the` front wall of thebeain and of bracket 4ll is provided with integralpads 6 and 7, respectively, to which maybe bolted the cylinder brackets 8 and `9. IBetweenthc pads 6 on the beam bodyIprefer to provide one or more openings [1 0 and similar open reservoir or housethe latter if desired and in the drawings partitions 13V extend bef tweenthe frontand rear `walls and between the top; aiidbottom walls A of the be'a'm, thereby formingii rectangularzreservoir to which pipes 14 lead Ifrom the air cylinders 3 and an outlet pipe l5 leadsgto the lair brake system orl other application of vthe air.

Obviously, a Y separate reservoirncoirld be seated in VaY suitable recess in 'the beam similarly.. to Athe .mounting of cylinders 3 and various" other modifications in the details of my invention will suggest themselves to those familiar with the art. I contemplate the inclusion of such modifications Within the scope of my invention as claimed.

I claim:

l. A locomotive pilot beam provided with a recess adapted to receive a pump cylinder, a cylinder mounting' flange on said beam adjacent said recess, said flange and the wall of said recess being perforated to facilitate the circulation of air about an adjacent pump cylinder.

2. A locomotive pilot beam provided with a recess adapted to receive a pump cylinder and provided With an opening adjacent said recess to permit the passage of air through the beam to a cylinder mounted therein.

3. A locomotive pilot beam provided with a recess adapted to receive a pump cylinder, and a shield on said beam extending outwardly from said recess.

4l. A locomotive pilot beam having an upwardly opening recess between its front and rear wall, and integral flanges extending upwardly from the sides of said recess, said recess and flanges being adapted to receive and mount the steam and air cylinders of an air pump.

5. In a locomotive pilot beam, an integral vertical bracket projecting upwardly from the top of the beam near the front thereof, and spaced reinforcing flanges extending rearwardly and downwardly from said bracket to the top of the beam, the top of said beam being recessed between said flanges.

6. In a locomotive pilot beam, a vertical bracket projecting upwardly from the top of the beam near the front thereof, and spaced reinforcing` flanges extending rearwardly and downwardly from said bracket to the top of the beam, the top of said beam being recessed between said flanges and the front of said beam being aperturecl below said bracket to provide an air passage to said recess.

7. In combination, a pilot beam provided with a recess, a projecting flange on said 'beam adjacent said recess, and a pump seated in said recess with its projecting portions shielded by said recess flange.

8. A locomotive pilotbeam having a recess to receive a fluid pump and provided with a fluid reservoir adjacent to said recess.

9. A locomotive pilot beam having a recess to receive a fluid pump and enclosing a fluid reservoir adjacent to said recess.

10. A locomotive pilot beam having recesses near its ends to receive fluid pumps and forming a fluid reservoir between its recessed portions.

11. A locomotive pilot beam of boxshaped cross section provided with a lateral bulge intermediate its ends, the top wall of said beam having an opening adjacent to said bulge, and upstanding brackets on said beam surrounding said opening.

12. A locomotive pilot beam of boxshaped cross section, the rear wall of which is provided with an outwardly bulged portion, the rupper wall of the beam having an openingadjacent to said portion, and integral upstanding brackets on said upper wall surrounding said opening.

13. In combination, a pilot 'beam provided with a recess, a shield on said beam extending outwardly from said recess, and a pump mounted on said shield and extending into said recess.

14. In combination, a pilot beam provided with a recess, a shield on said beam extending outwardly from said recess, and a pump secured to said beam and shield and extending` into said recess.

15. In combination, a pilot beam provided with a recess, a shield on said beam extending outwardly from said recess, and a pump mounted on said shield and extending into said recess, said beam being apertured adjacent to said pump to admit air to the same.

16. In combination, a pilot beam having a hollow portion forming a fluid reservoir and having a recessed portion adjacent thereto, and a lluid pump mounted in said recessed portion and connected to said reservoir.

17. In combination, a pilot beam having a hollow portion forming a fluid reservoir and having recessed portions adjacent each end thereof, and fluid pumps mounted in said recessed portions and connected to said reservoir.

18. In combination, a pilot beam of boxshaped cross section, the rear wall of which is provided with an outwardly bulged portion, the top wall of said beam having an opening adjacent to said portion, upstanding brackets on said upper wall surrounding said opening, and an air pump substantially enclosed by said portion and brackets.

In testimony whereof I hereunto aflix my signature this 28th day of May, 1924.
